Europeans manage with one button for toilet door, somehow

It's a question that's screwed with the head of every rail passenger since the Locomotion chugged through Darlington some two centuries ago; what kind of toilet needs three buttons to operate the bleeding door?

It's led to many a red-faced incident of ladies and gentlemen been caught in an excretory situation, or one that's involved burping the worm. Who wants to go to the toilet on a train and leave the door unlocked anyway? Only the British it seems - our European counterparts have far more sense in their skulls:

Yes, the Europeans get by with a toilet door that requires the operation of just one button. Those bloody foreigners, with their under-complicated locking mechanisms. Who won the war, anyway? Etc. There's a prize to anyone who photographs a toilet door requiring four buttons to open and close it. A real prize, too. Not like last time.

Thats a Swedish train i believe , and its far more efficient over there :D
My Mrs is Swedish and were moving there with my daughter next week thank f00k :D
Had enuff of the overcomplicated British system these days :)
